Week 05

Personal and Group Assignment

This week’s personal assignment was to design, document and 3D print an object, as well as 3D scan an object.

What is Additive Manufacturing?

It is a much more complex and in-depth industrial manufacturing process, including the entire print workflow. It encompasses multiple processes, while 3D printing refers to only a small part of the process. These operations involve more than creating 3D models, which can include: Modeling (CAD drawings).

How does it work?

To create an object using additive manufacturing, you must first create a design. This is usually done using computer aided design, or CAD software, or by taking a scan of the object you want to print. Software then translates the design into a layer by layer framework for the additive manufacturing machine to follow. This is sent to the 3-D printer, which begins creating the object immediately.

What was used for this task?

Bambu Lab P1S

Bambu Studio Slicer

Shapr3D

Designing your 3D Model - Articulated

First, we need to design our 3D model

01. Sketch

First, we need to make our sketch in CAD.

02. Extrude

Then, we need to extrude it

03. Dividing

Now, you need to divide the piece in as many parts that you want.

04. Adding connections

After that, you have to add the pieces that will be joining.

05. Export

To be able to print it, you need to export it as a STL file, so the printer can read it.

Designing your 3D Model - Solid

First, we need to design our 3D model for printing.

01. Sketch

First, we need to make our sketch in CAD, here I used Shapr3D.

02. Extrude

Then, we need to extrude it

03. Unifying

As we extruded in different heights, we need to unify the whole piece to make sure it prints as one piece.

04. Export

To be able to print it, you need to export it as a STL file, so the printer can read it.

3D Printing Slicer Process

To prepare my model for printing, I used Bambu Studio. Here is the step-by-step configuration for the Bambu Lab P1S.

01. Import

I selected the 0.12mm Fine @BBL X1C profile. The layer height is set to 0.12 mm for high detail, with an initial layer height of 0.2 mm to ensure good bed adhesion.

02. Quality settings

I selected the 0.12mm Fine @BBL X1C profile. The layer height is set to 0.12 mm for high detail, with an initial layer height of 0.2 mm to ensure good bed adhesion.

03. Strength settings

In this tab, parameters like the number of walls and the percentage of infill are adjusted to balance the part's durability and material usage.

04. Speed settings

Speeds are configured based on the type of filament and desired quality. Standard flow is maintained for consistent results.

05. Support settings

I enabled Tree Support with a branch distance of 5 mm and a branch angle of 45°. This ensures the overhanging parts are well-supported with minimal material usage.

06. Slice plate

Once all settings are ready, I click on Slice plate to generate the G-code and preview the estimated printing time and filament usage.

07. Print plate

Selecting Print plate opens the final dialog to check the printer status and plate type (Bambu Textured PEI Plate) before sending the job.

08. Send Printing

Finally, I click Send to transfer the file via Wi-Fi to the Bambu Lab P1S and begin the print job.

3D Scanning

It is a process of analyzing an object from the real world, to collect all the data in order to recreate its shape and appearance, digitally. Thanks to this process, the object can become a 3D model, which could help you as a base for the 3D project you are about to develop, but it can also be useful to reconstruct, analyze, or simulate ideas.

I'll be using "3d Scanner App"

Step by step scanning Lego Batmobile

Step 1: Download the app

Step 2: Open it

Step 3: Start scanning

Step 4: Process it

Step 5: Preview

Step 6: Export
